What are some puzzles that leave very little room for error?

Just recently I was rather upset that I had to rescramble the Petaminx and start from the beginning due to an error in my algorithm where I couldn't backtrack and understand how to fix it that otherwise I would've solved it. Needless to say, The Petaminx with how much it leaves very room for error makes it very stressful to solve and that fact it's so big that it takes hours upon hours to solve for me just shows that one wrong move could have a lot of problems. On top of the fact that pieces get jammed in the middle of the algorithm causes muscle memory to fade. With that being said, I will eventually convince myself to solve the Petaminx later on but it just comes to show that massive cubes that can be jammed could be quite a nightmare to solve. Also, not to forget the chance of it popping is another nightmare on it's own. So this discussion revolves around cubes that can be a nightmare to solve due to circumstances that will make you start over. Any other puzzles that fit this criteria?
 
Square-1 definitely fits this description. You can solve perfectly from start to finish, but if you make a minor mistake on the very last algorithm, it can lead to having to start over from scratch. From square one, you could say.
Nah square-2 is worse imo. At least on square-1 you have the (bandaged?) corners stopping you from turning at a slight misalignment, while on square-2 you don't have that and it's easier to misturn by 1 tick

2x2 if you wanna be world class

for general solving I'd say that one puzzle that's a circle and the carbon fiber stickers have to be oriented in the same wave with a lot of turnable faces.
 
From a learning standpoint. Fto and Square one were the most frustrating in terms of just having to scramble and restart. Square one because of how easy it is to read an alg wrong, and fto because of how disorienting it was. I think it's cool how careful you have to be in clock aswell. at the competitive level its all about those miniscule moves, and having to be so precise.
 
Maltese gear.

Honestly it is such a foreign and bizarre puzzle that it would honestly make for a good event. No moves are bandaged, and there's no awkward jumbling that blocks turns and leads to issues of possible legal and illegal moves. The maltese gears allows every turn on the quarter turn.

One wrong turn and you're absolutely fried.

In my opinion, the pyraminx is rlly easy
if u mess up, idk what is wrong with u

Pyraminx and petaminx are two very different puzzles.

Petaminx is a 9x9 megaminx equivalent.
